Disease burden refers to the impact of a health problem on a population, measured in terms of morbidity, mortality, and financial costs. It helps public health officials understand how diseases affect communities and prioritize resources for prevention and treatment. Common metrics used to assess disease burden include disability-adjusted life years (DALYs) and quality-adjusted life years (QALYs). This concept encompasses both the direct effects of diseases, such as cancer or diabetes, and the indirect effects, like lost productivity and emotional distress. By analyzing disease burden, researchers can identify trends, allocate funding, and develop effective health policies to improve overall community health.
